A few days ago my empeg suddenly started making an awful noise right in the middle of playing a song which had always worked fine. Since then, it won't boot anymore. It gets as far as starting the player app and then it hangs in an endless loop saying "Loading music databases..." and "Loading playlist..." over and over again.

At the console, the following messages are displayed:

The last part (starting with the line "player.cpp etc...") is repeated over and over again.

This has got me scared. Could the filesystem be corrupt? Would it be safe to reinstall an image? How can I determine whether a corrupt filesystem is indeed the problem and if so, how can I fix it and is there any chance of compounding the problem by trying?

Thanks in advance for any help anyone can give!

Oops. I found out how I could get a command prompt (pressing Ctrl+C instead of q), but when I then tried running fsck, this happened:

Bus error
empeg:/empeg/bin#

After that, any attempt to run fsck.ext2 resulted in a similar error message, even when I just tried "fsck.ext2 -?"!

Help!?!?!

Okay. That looks ugly.

You might want to check for a loose cable / bad solder connections on the IDE port. If this was a sudden loss, you might just have a connection problem on the IDE bus.

I've tried tightening all the IDE connections, but that didn't make a diference. Both harddisks spin up and are found by the kernel while booting. The IDE socket on the motherboard appears to be correctly attached to the motherboard, I don't see any pins that are loose.

I've tried checking the filesystem (which worked), but it didn't find any errors, at least not on /dev/hda4, /dev/hda6 and /dev/hdc4.

Fdisk claims that /dev/hd[ab]3 is of type OPUS, is that correct?

Also, when I try to check any of the other paritiions that fdisk claims are "Linux", fsck complains that it can't find the superblock, is that correct too?

My last resort was trying to reinstall version 2.0-b13 of the software to see if that made a difference (perhaps the boot partition had become corrupted or something), but to no avail, the problem is still unchanged.

I can't think of anything else to try! Help! Has my empeg died?

Is Rob doing support again?

Reinstall the player software (this won't wipe out your music) from the .upgrade file again. The player executable looks corrupted, or else the DRAM is getting errors.. most likely the latter.

-ml

I already tried reinstalling the player software, that didn't work. So it looks like it's the DRAM... :-( Is Rob once again providing support?

Ooops.. SRAM, not DRAM (my mistake). That's my guess as to the possible problem, but I might be wrong. Anyone else got a better suggestion?

Rob is not yet providing support.

Cheers

Oh yeah..

Have you installed the car2-developer image for v2-final yet?

If not, do so, If that succeeds in installing, then the issue likely is NOT the SRAM, but rather some corrupt data somewhere.

In which case, delete the database files and let the player try to rebuild them. If that fails, then you can always rerun the disk builder to wipe everything clean and start over. Sure beats replacing the SRAM..

Cheers

You might also want to try running the self tests. A control T at boot should give it a good test. I *think* there is another one that does just memory, but I do not remember (no pun intended) at the moment.

I meant to say that I could reinstall the software, but the problem was still there afterwards. I had already installed v2.0-final, but went back to beta 13 because of problems with the tuner in the final version. I'll give installing the final version a try (and if that fails, 3.0-alpha), I'm pretty much grasping at straws now... :-(

If you can reinstall software, then RUN THE DISK BUILDER and WIPE EVERYTHING CLEAN!!!

Cheers

That would be the last resort, it would be a *huge* pain in the ass to have to upload all my music again, especially if I would then discover that it was a hardware problem after all...

I think I've cracked it! In the FAQ (thanks Tony!) I found that you can start the player with -i to make it not read the current playlist. It was enough to do that once, now it boots again. The first thing I'm going to do is make a backup of the disks now...

Is there a way of obtaining a new IDE cable, other than through Rob? I suspect that a bad cable caused the problem in the first place so I want to replace it as soon as possible.

I found that you can start the player with -i to make it not read the current playlist. It was enough to do that once, now it boots again.

There's a chance that the problem was an incompatible MP3 file. Do you happen to know which track it was trying to play? Perhaps that track simply needs to be deleted from the player.

I think it had played the offending track succesfully previously. Also, the crashes trying to run fsck make me think it was originally a hardware problem. I suspect that it was the IDE cable. Does anyone have a spare IDE that they would be willing to sell me or is there some other way of obtaining one?

I suspect that it was the IDE cable.

There is a large list of things that could cause disk drive trouble, make sure to go through the list carefully.

Does anyone have a spare IDE that they would be willing to sell me or is there some other way of obtaining one?

You could try simply squeezing it, too...
